On January 28, on the fourth day of the lunar new year, people chatted with their relatives via tablet or computer video to pay new year calls. In response to the call of "no door-to-door, no dinner party" in recent days, the citizens of our city have consciously changed the traditional way of Spring Festival, such as visiting relatives and friends in the previous Spring Festival, and paid new year calls with computers, mobile phones and other carriers at home, so as to support the prevention and control of the new coronavirus infected pneumonia epidemic with practical actions.
